The conservation equations of Fluid Mechanics in unsteady state are employed in the theoretical reconstruction of an experiment proposed by Galileo, to investigate the forces acting on a twin-pan type of balance, with a counterweight in one extremity, and two buckets in the other extremity, hung in the same vertical, where the water jet issuing from an orifice in the bottom of the upper bucket strikes the lower bucket. The result of this analysis revealed that the method proposed by Galileo for the calculation of the percussion force is incorrect. The analysis also revealed that the net force during the process is practically null, which would make Galileo's account of the major movements of the balance credible, despite his having not identified all the forces acting on the system.
